As the introduction of back with reference to figure 4, optimization control module 2a detection CAD unit 2b is according to the correlationship between the processing cost information of the cad data of the design data generation of vibration-absorptive material 4, the mechanical response amount that mechanical response amount computing unit 2c detects, the processing decision information of processing decision-making detecting unit 2d detection and pricing unit 2e detection.Optimization control module 2a changes the cad data of vibration-absorptive material 4, until the optimum shape that detects vibration-absorptive material 4 according to correlationship.With the optimum shape of vibration-absorptive material 4, vibration-absorptive material 4 is machinable, and the mechanical response amount satisfies the design data of vibration-absorptive material 4, and has realized minimum manufacturing cost with vibration-absorptive material 4.Optimization control module 2a upgrades previous correlationship according to processing decision information and the new processing cost information that detects of pricing unit 2e that the cad data that changes, the new mechanical response amount that detects of mechanical response amount computing unit 2c, processing decision-making detecting unit 2d detect once more.Optimization control module 2a carries out the optimization arithmetic operation according to the correlationship of upgrading to the optimum shape detection of vibration-absorptive material 4.With the optimum shape of vibration-absorptive material 4, the mechanical response amount satisfies the design data of vibration-absorptive material 4, and vibration-absorptive material 4 is machinable, and has realized minimum manufacturing cost with vibration-absorptive material 4.
In the present embodiment, it is whether machinable that processing decision-making detecting unit 2d detects vibration-absorptive material 4, make when from pressing mold, taking out vibration-absorptive material 4, after the outer periderm of the transverse shape of transversal section is divided perpendicular to a plurality of planes of Fig. 3, Fig. 5, Fig. 6 and draw-off direction a shown in Figure 7, during from draw-off direction a projection, periphery is not intersected with each other.
In the present embodiment, with reference to the mechanical response amount that detects by mechanical response amount computing unit 2c, mechanical response amount computing unit 2c be set at detect in the shock of a fall creeping displacement that produces in maximum deceleration that the content 5 by vibration-absorptive material 4 packagings produces and maximum displacement and vibration-absorptive material 4 long-term the uses one of them.
To introduce process instance with reference to figure 2 then, detect the optimum shape of vibration-absorptive material 4 according to optimum shape designing method of the present invention.In step S1, by the keyboard of input equipment 1 or by the design data of communication line such as the Internet input design object vibration-absorptive material 4.
For example, under the situation of the optimum shape that designs damping packaging vibration-damping material 4, as design data, the shape of input content 5, weight, the height of fall, the direction of falling and design margin are (for example, mechanical response amount limit, maximum deceleration such as content 5 generations, the maximum displacement of content 5 is to judge whether content 5 drops out bottom or vibration-absorptive material 4, and the permanent strain of the creeping displacement of vibration-absorptive material 4) and engineering properties value (for example, the stress of inside and outside material therefor of casing and vibration-absorptive material 4 to judge that vibration-absorptive material in the long-term use 4 produces, damping thickness and maximum deceleration, maximum instantaneous strain and creep strain).Also import when needing outer container such as the size of corrugated board box, content 5 in outer container residing position etc. as design conditions.
Engineering properties value for outer container and vibration-absorptive material 4 material therefors, the memory device or the database file of engineering properties value several data have been prepared storing, according to used material, by from memory device or database and file search engineering properties value, just can use these engineering properties values.
After having imported above design data, flow process proceeds to the step S2 of Fig. 2, uses CAD unit 2b to produce cad data M1 for example shown in Figure 3 early stage design phase shape as vibration-absorptive material 4 in calculation process equipment 2.At this moment, shape data (for example, the size in muscle rib or hole, angle and have or not) is defined as design parameter.
Can select cad data M also to be used as the shape of early stage design phase from database for previous design casing, rather than adopt the new method that produces early stage design phase shape.In this case, select a plurality of different early stage design phase shape of the vibration-absorptive material 4 stored in Fig. 3 and the database shown in Figure 7, the shape data that comprises in the described a plurality of selected early stage design phase shape of vibration-absorptive material 4 and each the early stage design phase shape can be defined as design parameter.
Then, flow process proceeds to step S3, step S4 and step S5, in step S3, step S4 and step S5, respectively the cad data M that defines among the design data imported among the step S1 and the step S2 is carried out following processing.
In step S3, the cad data M Computational Mechanics response amount of mechanical response amount computing unit 2c to defining among the step S2.Computational Mechanics response amount is used to contrast the maximum deceleration that design margin and content 5 produce etc.
In the calculating of mechanical response amount, suitably import the mechanical response amount of the engineering properties value correspondence of vibration-absorptive material 4 material therefors then and there, perhaps from system database, search for the mechanical response amount of vibration-absorptive material 4 material therefor correspondences in the previously stored engineering properties value and import the mechanical response amount with search engine, perhaps when the mechanical response amount of vibration-absorptive material 4 material therefors is represented by relational expression, by relational expression Computational Mechanics response amount.
On the other hand, in step S4, processing decision-making detecting unit 2d is by detecting with pressing mold processing vibration-absorptive material 4 time, whether provides the used extraction gradient of the demoulding rightly and detect the processing decision-making in the cad data M of step S2 definition.
In plasticity detects, can use a kind of program, after checking a plurality of planes division of cross sectional area quilt perpendicular to draw-off direction a of vibration-absorptive material 4 transversal section, whether reduce gradually along draw-off direction a, the periphery of transversal section or whether any one intersects with another periphery or interior week in interior week simultaneously also can be passed through some CAD software of application (Solid Works for example; The trade name that SolidWorks company produces) the extraction gradient that is equipped with is confirmed function and is carried out described detection.
In step S5, pricing unit 2e is to the cad data M calculating processing cost of step S2 definition.For example; be used as under the situation of vibration-absorptive material 4 in pearl foam compression-moulded product; the numerical value that the volume of the cad data M of material use amount correspondence multiply by the material unit cost is used as material cost, and the operating cost of molding press etc. is used as processing cost, has therefore calculated processing cost.
Be used as under the situation of vibration-absorptive material 4 in the crushed foam compression-moulded product, the numerical value that the volume of the cad data M of material use amount correspondence multiply by the material unit cost is used as material cost, cutting cost, heat bonding cost, demoulding cost etc. are used as processing cost, have just calculated processing cost.
Then, flow process proceeds to step S6.For example, use mechanical response amount, processing decision information and the processing cost information calculated among step S3, step S4 and the step S5, draw out the correlationship between design parameter, mechanical response amount, processing decision-making and the processing cost of cad data M1 shown in Figure 3, as shown in Figure 4.Determine the optimum shape of vibration-absorptive material 4 according to described correlationship.With described optimum shape, vibration-absorptive material 4 is machinable, and the mechanical response amount satisfies the design margin of vibration-absorptive material 4---design object, and processing cost is minimum.
In the optimum shape of determining vibration-absorptive material 4---in the process of design object, if design conditions does not satisfy, cad data M2 as shown in Figure 4 and Figure 5 (can't process) because the mechanical response amount surpasses design margin, perhaps exist the vibration-absorptive material shape that can further cut down finished cost, flow process is just returned step S2 from step S6, until having determined optimum shape.As shown in Figure 4, change cad data M,, finally determine optimum shape so that upgrade the correlationship between mechanical response amount, processing decision-making and the processing cost.
In the state that Fig. 4 shows, optimization starts from cad data M1 shown in Figure 3, cad data M1 change into successively cad data M2, M3 ... M8 has for example obtained the cad data Mopt of vibration-absorptive material 4 optimum shape shown in Figure 6 in the 9th suboptimization.In order to determine optimum shape---the design object of vibration-absorptive material 4,2a has used general optimum procedure to the optimization control module, such as iSight (trade name is produced by Engineous Software company).
